Technical Field

[0001] This utility model relates to the field of outdoor power distribution box technology, specifically an outdoor power distribution box. Background Technology

[0002] Outdoor distribution boxes are electrical devices used in outdoor environments, primarily for distributing and controlling electrical energy.

[0003] To prevent unauthorized personnel from opening outdoor distribution boxes, the boxes are equipped with lockable doors. Additionally, viewing windows are provided on the doors to facilitate observation of the instruments inside. However, these windows cause light pollution at night and allow sunlight to directly penetrate the boxes during the day, affecting heat dissipation. Using a door without a viewing window would be inconvenient, requiring a key to unlock and lock the door each time the instruments are read.

[0004] Based on the above situation, designing a power distribution box that can be sealed to provide shade and allows observation of the instruments inside the box without unlocking the door is a problem that urgently needs to be solved in the existing technology of outdoor power distribution boxes.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1 and Figure 2 An outdoor distribution box includes a box body 1, which is installed on an outdoor wall or pole. A door 2 is hinged to the box body 1. The door 2 has a locking mechanism, which is existing technology and will not be described in detail here. The locking mechanism can lock the door 2 when it is closed. A transparent window 201 is provided on the door 2 for observing the instruments inside the box body 1 from the outside. The inner side of the door 2 adopts a concave design, so that there is space on the inner side of the door 2 to arrange structures such as a light shield 3. The inner side of the door 2 is provided with a light shield 3 that can move up and down to block the light from the transparent window 201.

[0027] like Figure 1 , Figure 2 and Figure 4A raised plate 301 is fixedly connected to the light shield 3. A fixed sleeve 4 is fixedly connected to the inner side of the door 2. A return spring 5 is fixedly connected to the bottom of the inner wall of the fixed sleeve 4. A movable connecting rod 6 is fixedly connected to the top of the return spring 5. The top of the movable connecting rod 6 passes through the top of the fixed sleeve 4 and is fixedly connected to the raised plate 301. The return spring 5 has an upward pushing force on the movable connecting rod 6 and the raised plate 301. A control pull rope 7 is fixedly connected to the bottom of the raised plate 301. The control pull rope 7 is connected to the center of the bottom of the raised plate 301. The bottom of the control pull rope 7 extends to the outside of the door 2.

[0028] like Figure 2 The inner side of the box door 2 is fixedly connected to a limiting groove rail 8, and the bottom of the light shield 3 is fixedly connected to a vertical connecting plate 9. There are two sets of limiting groove rails 8 and vertical connecting plates 9, which are symmetrically arranged on both sides of the control pull rope 7. A protrusion block 10 is fixedly connected to one side of the vertical connecting plate 9. The protrusion block 10 and the limiting groove rail 8 are slidably connected, which can provide guidance for the movement of the vertical connecting plate 9, so that the vertical connecting plate 9, the protrusion plate 301 fixed to the vertical connecting plate 9, and the light shield 3 fixed to the protrusion plate 301 can only move in the vertical direction.

[0029] like Figure 2 and Figure 3 A fixing ring 11 is fixedly connected to the bottom of the inner side of the box door 2, and a sealing ring 12 is fixedly connected to the inner side of the fixing ring 11. The bottom of the control pull rope 7 passes through the sealing ring 12, which can ensure the sealing between the control pull rope 7 and the box door 2 without affecting the movement of the control pull rope 7.

[0030] like Figure 2 and Figure 3 A limiting protrusion 202 is fixedly connected to the inner side of the door 2 and above the transparent window 201, which can limit the maximum distance of the light shield 3 to move upward. When the top of the light shield 3 moves upward and contacts the limiting protrusion 202, the light shield 3 can just close the transparent window 201. A sealing strip 13 is provided on the outer surface of the box body 1 to cooperate with the door 2, which can improve the sealing between the door 2 and the box body 1.

[0031] like Figure 1 The enclosure 1 is fixedly connected to a partition 14. The interior of the enclosure 1 is located above the partition 14 to form an instrument installation area. When the instrument is installed in the instrument installation area, it can be observed through a transparent window 201. The partition 14 is provided with a wire slot 15 to facilitate wiring between the instrument and the electrical equipment below the partition 14 inside the enclosure 1.

[0032] like Figure 2 , Figure 3 , Figure 5 and Figure 6The bottom of the control pull rope 7 is fixedly connected to an elastic rope 16. The elastic rope 16 has an elastic coefficient suitable for actual needs, and its elastic coefficient does not exceed the elastic coefficient of the return spring 5. The bottom of the elastic rope 16 is fixedly connected to a hook ring 17, and the bottom of the box 1 is fixedly connected to a positioning ring 18. One side of the positioning ring 18 is provided with a hooking slot 181 that works with the hook ring 17. When the observation instrument is not needed, the hook ring 17 can be put on the positioning ring 18. Under the elastic contraction of the elastic rope 16, part of the hook ring 17 is locked into the hooking slot 181 to prevent the hook ring 17 from loosening. At the same time, the part of the control pull rope 7 located outside the box door 2 will not become tangled.

[0033] The working principle of the outdoor power distribution box provided by this utility model is as follows:

[0034] When the hook ring 17 is hooked onto the positioning ring 18, the tension of the return spring 5 will push the movable link 6 upward. The movable link 6 will drive the protruding plate 301 and the light shield 3 to move upward, so that the light shield 3 blocks the transparent window 201. At this time, the light emitted by the instrument inside the box 1 cannot be diffused to the outside of the box 1 through the transparent window 201, and sunlight cannot shine into the inside of the box 1 through the transparent window 201 during the day.

[0035] If it is necessary to observe and read the instruments inside the enclosure 1, the hook ring 17 can be removed, the hook ring 17 and the control rope 7 can be pulled down, the control rope 7 can be pulled down the protruding plate 301, which will cause the light shield 3 to move down and separate from the transparent window 201. At this time, the instruments inside the enclosure 1 can be observed and read without unlocking and opening the enclosure door 2.

[0036] Compared with related technologies, the outdoor distribution box provided by this utility model has the following beneficial effects:

[0037] This invention employs a concave design on the inner side of the door 2, along with a light-shielding plate 3 located inside the door 2. When instrument observation or reading is required, the control rope 7 can be pulled down to move the light-shielding plate 3 downward and separate it from the transparent window 201. This allows for quick observation and reading of the instrument without opening or unlocking the door 2. When instrument observation is not required, the light-shielding plate 3 moves upward under the action of the return spring 5, closing the transparent window 201 from the inside. This avoids light pollution caused by the instrument emitting light at night and prevents sunlight from directly shining through the transparent window 201 into the interior of the enclosure 1 during the day, thus ensuring the heat dissipation capacity of the enclosure 1.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
